" of attachment either directly to an electric lamp or an electric fixture the lamp.

-Lamp shades when supported by an electric lamp are known as clamp shades and when attached to an electric fixture they are known as bridge shades and it is another object of .the'present invention so to con-.' struct a lamp shade that it. may be used .in

either manner thereby roviding a combined clamp and brid e shadg.

A further ob]ect of the invention resides in a novel construction whereby the shade be rigidly supported from either the clam or bridgesupport.

W1ththe above and other objects in view reference wil? be had to the accompanying drawing in which .the invention is illusindependently of trated in various forms and in which,

Figure 1 is a perspective view of a lam shade frameconstructed in accordance wit the present. invention,

a Figure 5. is a fra enta top plan view illustrating a slight y modi edformof the invention,

Fi re 6 is a top plan view of a still further modi ed form of the invention, and;

Figure 7 is a fra a still further m tion. y

Referring-to the drawing by reference characters and particularly to the 'constructlon illustrated in Figures 1 to 4 inclusive, the reference numeral 10 designates a clamp attachment and 12 desi ates a bridgeat tachment. The lamp s ade frame in the present illustration is of circular form and comprises two members '14 and 16 hedd in ified form o the invenentary top lan view of spaced relation by braces. 18, all of which, is

of conventional construction.

The clamp member 10 consists of two sub-- stantially circular lamp embracing members 20. These members 20 are secured in the frame by means of extensions 22 which are rigidly attached to the frame as at 24 by welding, soldering or in any other manner.

The bridge member 12pis' formed from sheet metal and comprises a body. ortion 26 from which projects a flange 28 w ich is i nternally threadedfor en agement with an external. thread with whic the conventional. lamp socket is formed. The bridge attacli ment 12 is preferably circular inform and has extensions 30 projecting therefrom at diametrically opposltepoints. These extensions 30% are .so constructed that they may be bent around the extensions 22 of t e clamp attachment as best illustrated at 32 in Figure 2. By this construction the bridge attach-.

.ment 12 is attached to the clam attachment 1 i 10 and in order to insure rigi attachment to the bridge attachment 12 the extensions 30 may, if desired, be welded, soldered or in other ways rigidly attached to the extensions The clamp attachment being rigidly at.- tached as. at 24 to the member '14 as heretov fore described and the bridge attachment being rigidly attached as heretofore described, the two-attachments will notonly be rigidly carried by the lamp shade frame, but will be v rigidly attached to one another.. I

When the devicei's employed as illustrated r in Figure 1, the members 20 are merely spread 1 and engaged with the outer face of an electric lamp such as A. ,When; however, the shade is to be used in combination with the socket of the lamp the thread indicated B in Figure 1 and wlth whichthe lamp socket of conventionalform is provided is engaged with the-thread 0 upon the interior of the. flange 28 thus supportingthe shade from the socket;

In that form of the invention illustrated in Figure 5, the bridge attachment is designated 40. Itis flanged as at 42 and said flange is 1 provided at diametrically'oppositepointswith openings 44. The clamp attachment is formed by the loops in the manner heretofore described but in this construction the extensions 22 are spread at the bridge fixture as indicated. These extensions 22 extend in opposite directions in pairs and the extensions of each pair converge and are secured to the lamp shade in the same manner I as heretofore described. The extensions 22 mayor may not be secured to the flange 42 i the bridge attachment is provided at diametrically opposite points with openings 54 through which the extensions 22 pass. This form of the-invention differs, however, from that form illustrated in Figure 5 in that the extensions 22 pass through the openings 54 in parallelism and in contact with one another instead of being spread as in Figure 5.

To provide for rigid attachment of the clamp attachment to the bridge attachment, clips 56 are provided. These clips 56 comprise a portion 58 which is adapted to Wrap or fold around the extensions 22 and which may be secured to the extensions 22 by welding or soldering as desired. Projecting, from the body portion of these clips 56 there are fingers or like members 60 which underlie the flange 52 and ma be rigidly secured thereto by welding, so dering or in any desired manner.

It is to be'understood that the ends of the extensions 22 are secured to the frame as heretofore described, after which the members 20 of the clamp attachment may be spread to embrace a lamp as heretofore described.

In the form of the invention illustrated in Figure 7 the bridge attachment is of rectan- "gularform. It comprises a body portion 62 aving a circular opening 64 whlch is provided with a depending. flange as heretofore described. In this form of the invention the extensions 22 of the clamp attachment 10 extend parallel with opposite side edges of the bridge attachment 62'as il-' lustrated at 68 in the drawing. The clamp attachment and bridge attachment are secured together by bending of portions 70 of the opposite side edges of the body portion 62 around the extensions 22. This action may, if desired, be welded or soldered in order to provide rigidity.

As in that form of the invention illustrat-- ed in Figure5, the extensions 22 in this last described form of the invention extend in opposite directions in pairs and the extensions of each air. converge and are rigidly secured to the rame member 14 of the frame. I In each of the forms of the invention the lampshade in which the lamp s 66 threaded From the foregoing it will be apparent that the present invention providesanew and improved combination clamp an'd'brid e ade may attached and supported eitherfrom an electric lamp or from an electric lamp socket without necessitating change in the shade structure.

While the invention has been herein illustrated in its preferred forms it. is to be understood that it may be practiced in other forms without departing from the spirit thereof and that the invention is not to be limited to the specific details of construction herein illustrated. I
